Window glass channel lining

WINDOW GLASS CHANNEL LINING Filed March 14, 1956 ipr M Patented Oct. 27,1936 UNITED STATES PATENT -OFFlCE 3 Claims.

This invention relates to certain improvements in weather strips orlinings for window glass channels of the general type shown in mypending application Serial No. 60,783, filed January 25, 1936, which areemployed to cushion and guide the glass at the sides of a deep channel,in which an edge guide for the glass, if employed at all, is separatefrom the guiding means which engage the sides of the glass.

When weather strips or linings of this type are installed, it isfrequently necessary to cut the strip at an oblique angle, and anobjection to the type of strip shown in my said application is to theeffect that the tongues of the core, when out from the continuous edgeportion, are liable to become disconnected from the wire, or bead towhich their ends are connected, and because they are unsupported at bothends, are liable to become a source of noise in a moving automobile.

The objects of my invention are to provide a form of weather strip ofthe type above referred to, in which no metal parts are exposed, orrequired to provide an ornamental finish, and in which a metal core isprovided which is not notched, or slotted, but may nevertheless be bentsufiiciently to conform to the curvature of the window frame in which itis to be installed, without appreciable distortion.

I accomplish these objects by providing a core 'consistingof narrowstrip of thin sheet metal, the edge portions of which are bent reverselyonto the back side thereof, covering the face side there-- of with astrip of suitable cushioning fabric, the edge portions of which areextended about the reversely bent portions of the core and clampedbetween the edges thereof and the adjacent side of the core, theintermediate portion of the core being bent in transversely concaveformation on its face side, and a cushioning. shim strip beingpreferably provided in the cavity thus formed between the fabric and thecore.

For a more complete disclosure of the invention reference is made to thefollowing specification in connection with the accompanying drawing, inwhich:

Fig. 1 is a combined cross-sectional and perspective view, on anenlarged scale, of a channel lining embodying my invention.

Fig. 2 is a cross sectional view of a window channel in which the liningis installed and Fig. 3 is a view, similar to Fig. 1, showing the liningstrip in bent formation.

In the drawing, a common form of window frame a is indicated having adeep channel therein to the sides of which an embodiment of my inventionis applied.

According to my invention I provide a core I), which consists of anarrow strip of thin sheet metal of uniform width, both edge portions 0,c of which are bent, or rolled reversely in cylindrical form onto theback side of the strip and the middle portion of which between said edgeportions is bent in transversely concave form, at its face side, thereversely bent portions being slightly off set to form a sharp bend orangle between the cylindrical portion and the concave middle portion, asindicated at d, d.

A cushioning strip e, of suitable fabric, such as plush, or velvet,having a pile of suitable length, is arranged on the face side of thecore and its edge portions are extended about the reversely bentportions 0, c and between the edges of said portions and the back sideof the strip, at the apex of each angular portion d, d, and the fabricis securely clamped therebetween and stretched tightly between therounded surfaces of the portions c, c. On account of the formation ofthe core above described, there is a substantial space, or longitudinalgroove, between the inner side of the fabric and the concave side of thecore, in which a reinforcing cushioning strip or shim strip 1 ispreferably located, although the use thereof is not essential, as thefabric may be drawn from one edge of the core to the other sufficientlytightly to provide the desired cushioning effect, which dependsprincipally on the height and strength of the pile of the fabric. If theshim strip is employed a less expensive fabric usually may be employedand when the shim strip is employed the longitudinal cavity in the corewill hold' the strip in position without other securing means.

The concave-convex formation of the core is advantageous for severalreasons. It increases the rigidity of the strip in resisting bending indirections perpendicular to the plane of the strip, so that when thestrip is bent edgewise to conform to the curvature of a window frame, itis much less likely to become distorted. Also this formation enables theedgewise bending to be more easily performed, as there is practically noflat surface in the plane of bending. When the strip is bent, theconcavity of the core is slightly increased and the width of the core iscorespondingly reduced.

By providing the relatively sharp angular portions in the core againstwhich the fabric is clamped by the edge of the core the effectiveness ofthe clamping action on the fabric is increased. If the strip is securedin position by rivets passing through the middle of the strip the headsof the rivets may be depressed well below the surface of the fabric, sothat possibility of chattering against the glass will be avoided.

I claim:

1. A window glass channel lining comprising a core consisting of anarrow strip of sheet metal of uniform width having both of itslongitudinal edge portions bent reversely onto its back side and a stripof cushioning fabric on the face side of saidcore having itscorresponding edge portions extending about said reversely bent portionsand clamped between the edges thereof and the back side of the core, theface side of said core between said reversely bent portions beingtransversely concave, forming a longitudinal recess over which saidfabric is tightly drawn, the lining strip thus formed being adapted tobe bent in having its corresponding edge portions extending about saidreversely bent portions and clamped between the edges thereof and theback side of the core, the face side of the core between its reverselybent portions being transversely concave, forming a longitudinal recess,and a strip of cushioning material disposed in said recess beneath thefabric, the lining strip thus formed being bendable in curved formationin the plane of its sides.

3. A window glass channel lining comprising a core consisting of a sheetmetal strip of uniform width having both of its edge portions bentreversely in cylindrical formation with the edges thereof in proximityto its back side, said edge portions being ofl-set with relation to themiddle portion of the strip to provide a relatively sharp angularportion therebetween and a cushioning strip on the face side ofsaid-core having its edge portions extended about said core edgeportions and clamped between the edges of the latter and the apex of thecorresponding angular portion at the back side of the core.
